[Halld-cal] Working Group Meeting tomorrow at 11:00 am

[Alexander Somov]

Hello Elton,

Just a few comments regarding SiPM timing measurements:

1. Fernando found a problem with the particular preamp for the
3x3 sensor which we had used for the measurements (a resistor
burned down). Therefore, I would be 'skeptical' about current
3x3 SiPM results. We have just received two fixed preamps from
Fernando and are going to repeat measurements.

2. For the array studies we used not the latest preamp
version. The measurements will be updated as well.

Cheers,
       Sascha
